I recently purchased a 2001 Cavalier base with 48k miles & has a 2.2L OHV engine. This was my first Cavalier and I'm pleasantly surprised with it. One thing that I've noticed about this engine is the water temp creeps up a little higher than I'd like. Looking on my scanner, the water temp will run about 206 degrees f. The following is what I've done so far...⏎
- Replaced the OEM 180 deg thermostat. I compared the new thermostat to the original (in a pan of water on the stove with an accurate thermometer) and while both operated in approx. the same temperature range, the new one seemed to open further.⏎
- I went into the PCM program and set the cooling fan to switch on @ 198 deg f & off at 194 deg f.⏎

Its still doing about the same after trying the above. Yesterday, I noticed something interesting. It 'appears' the replacement water pumps may have a more efficient water pump impeller design. I borrowed the attached image from a You Tube video by Raw Customz where the gentleman is pointing out the difference that he noticed between the OEM & replacement WP impeller. The thought being that perhaps GM improved the impeller design to help the water flow at lower RPMs (which seems to be where the temperature is more prone to creep higher).⏎

My question is does any of the Cavalier gurus have any thoughts to offer? Either with the new water pump impeller designs or does anyone have any ideas or thoughts to offer.⏎

Thank you for your input..⏎
